If you call the LockWorkstation function from a screen saver (or while a screen saver is running), the computer locks as expected. However, the computer no longer responds to the CTRL+ALT+DELETE key combination. When this problem occurs, you must reset the computer.
This problem occurs because Winlogon enters a state in which secure attention sequence (SAS) key sequences are not processed. Other processes on the computer continue to run, and the computer continues to be accessible over the network.
